A number of owners of 2010 Ford F-150 trucks have complained to the National Highway Traffic Safety Administration (NHTSA) that an alleged glitch in their rear defrosters has caused their backlites to shatter or spiderweb in cracks in recent months. glassBYTEs.com™ originally reported about this issue in December 2013, and since then more than 30 F-150 owners have issued related complaints–totaling more than 50 now.
“While driving into work, [I] had the rear defrost[er] active for roughly ten minutes,” wrote one owner just last week. “At a stoplight, [I] noticed smoke rising from [the] outside of the rear window. As I proceeded to pull off the road, [I] heard a loud bang and the passenger side rear window proceeded to spiderweb. The gasket for the rear window has been burned on the lower left hand … I hope that Ford steps up and does something about this before someone actually gets hurt.”
Another owner wrote on November 11, “[The] passenger side rear window panel shattered with a loud bang when the rear defroster was turned on. There was a large 6×4-inch hole in the window and the balance was spiderwebbed.”
In October, another 2010 Ford F-150 owner complained that the “rear window defroster caught on fire and shattered [the] rear window glass” in the vehicle. “This could be dangerous and should be recalled,” continued the owner.
Similar complaints date back to October 2012.
According to NHTSA’s website, no recalls or investigations related to the complaints have been launched through the agency. At press time, officials from Ford had not yet responded to requests for comment.
